Frequently asked questions

Is formaldehyde safe during pregnancy?
Harmonised CLP (ECHA Annex VI) lists formaldehyde (CAS 50-00-0) with carcinogenicity (H350), mutagenicity (H341) and acute/toxic/sensitisation hazards but does NOT include a harmonised reproductive classification (H360/H361). Therefore there is no regulatory harmonised evidence to support a reproductive hazard classification; dermal/topical exposure from cosmetics is low but measurable (formaldehyde is volatile and can be taken up via skin or inhalation). Sources: ECHA Annex VI (harmonised CLP), ECHA H-codes.
Is formaldehyde safe while breastfeeding?
No harmonised reproductive or lactation-specific classification in ECHA Annex VI; no regulatory designation as a developmental or lactation toxicant. Exposure from topical cosmetics is low but measurable; maternal systemic uptake could plausibly result in low-level systemic exposure, but authoritative sources do not classify formaldehyde for reproductive/lactation hazards. Sources: ECHA Annex VI (harmonised CLP), PubChem GHS/ECHA hazard information.
Is formaldehyde safe for baby skin?
Harmful skin effects (H314/H317) and respiratory toxicity are harmonised hazards, but there is no harmonised reproductive/developmental classification. Because infant skin has higher permeability and higher surface-area-to-weight ratio, measurable dermal absorption leads to increased exposure scoring (+1 versus adult). Additionally, formaldehyde is an established skin sensitiser/irritant (relevant to infant skin). Sources: ECHA Annex VI (harmonised CLP), ECHA hazard information.
